Sludge, treated biowaste and soil - Determination of total nitrogen using dry combustion method
This European Standard specifies the determination of total nitrogen (organic and inorganic) according to the procedure of Dumas in sludge, treated biowaste and soil. A typical limit of detection is 0,02 % nitrogen, and a typical limit of quantification is 0,08 % nitrogen.
Schlamm, behandelter Bioabfall und Boden - Bestimmung des Gesamt-Stickstoffgehalts mittels trockener Verbrennung
Diese Europäische Norm legt das von Dumas entwickelte Verfahren zur Bestimmung des Gesamt-Stickstoffs (organisch und anorganisch) in Schlamm, behandeltem Bioabfall und Boden fest. Eine typische Nachweisgrenze liegt bei 0,02 % Stickstoff und eine typische Bestimmungsgrenze liegt bei 0,08 % Stickstoff.
Boues, biodéchets traités et sols - Détermination de la teneur totale en azote par combustion sèche
La présente Norme européenne spécifie la détermination de la teneur totale en azote (organique et inorganique) selon le mode opératoire de Dumas dans les boues, les biodéchets traités et les sols. La limite de détection type est 0,02 % d'azote, et La limite de quantification type est 0,08 % d'azote.
Blato, obdelani biološki odpadki in tla - Določevanje celotnega dušika z metodo suhega sežiga
Ta evropski standard opredeljuje določevanje celotnega (organskega in anorganskega) dušika v skladu z Dumasovo metodo v blatu, obdelanih bioloških odpadkih in tleh. Običajna meja detekcije je 0,02 % dušika, meja kvantifikacije pa 0,08 % dušika.
